Popis:	Salicylic acid (SA) and hydrogen peroxide (H2O2) are involved in similar signaling responses to stress. Previous reports demonstrated micro-tuberization induction by salicylates. Both SA and H2O2 induce similar long term signaling responses to stress. In the present work, the potential long term effect of H2O2 on the induction of micro-tuberization was evaluated. Nodal explants from micro-plants were immersed in H2O2 for 60 min and cultured on medium 30 d. Micro-plants obtained were sub-cultured on tuberization medium and incubated in darkness at 8 and 20 ± 1 C. Pretreatment with 5 and 50 mM H2O2 induced the highest micro-tuberization percentage at 20 C, when compared with other pretreatments at 8 C, 1, 5, and 50 mM. H2O2 significantly induced more weight per microtuber in all treatments at 20 C. H2O2 significantly enhanced sprouting of microtubers produced at 20 C.
